Abstract: During the last three years the possibility to produce a high density, high temperature plasma by the fast magnetic compression of a preheated plasma has won condiderable interest. The techniques for this type of experiment have been further developed, and extensive measurements have been made, mainly concerning the radiation of the plasma. Valuable information, in particular on the electron temperature and the variation of the electron temperature with time (1), and on the ion temperature (2) was accumulated. There have also been many attempts to measure the internal magnetic field and, if possible, the distribution of this internal field along a diameter of the plasma cylinder. This is of particular interest, since all observations show that an initial reverse field (3) is of great influence on the behaviour of the plasma and because there are some obscurities about the dissipation mechanism of the energy of the trapped reverse field. Reliable probe measurements could help to clarify this dissipation mechanism. In addition one could obtain the pressure distribution and the $\beta = \frac{nkT}{B^{2}_{z}/2/u_{o}}$ of the plasma. It would furthermore be possible to obtain information on the stability of the plasma cylinder and on eventually developing turbulence. So far all probe measurements in theta pinch devices have been considered as unreliable. There have been mainly the following objections: [...]
